The MadDad(TM) Metal V2 downpipe is one of the most well received hi-flow metal substrate downpipes in the Subaru performance community. In this recent update, we've add an auxilury 02 sensor optimized for wideband/percision tuning. The MadDad Metal V2 downpipe is the only downpipe on the market that was explicitly designed to minimize or eliminate boost creep that many Subaru owners experience, in particular with STi models. The unique arrangement of a metal substrate cat closer to the turbo, but combined with a catless wastegate ensures fast boost control response.

The MadDad(TM) Metal V2 downpipe is the only downpipe with a 14 DAY MONEY BACK GAURANTEE....EVEN AFTER YOU INSTALL IT. See if any other performance brand will dare to match it

If you want the absolute best Subaru downpipe ever made, buy this one. The fitment is perfect. The design is outstanding and one of a kind. The materials and welds are top notch. The heatshield makes passing visual inspection a non-issue. It's THE reference downpipe.

Fitment on this DP was perfect, performs well, looks good. Weld and flange quality is amazing, it is almost a shame its getting dirty on the car.

Only complaint is that with the design of the cat/catless waste-gate it is difficult to effectively wrap with header wrap. Managed to get it done but it took some working. The downstream heat-shield looks like a second cat (lets hope I can pass visual without removing it!)

Love it! Highly recomended. Also love the Whisper I have bolted to the end of this baby!
